As soon as the news hit the internet, fans were thrilled to learn that the friendship between her and SUGA is still going strong. It's no secret that the two have been great friends ever since BTS' collaboration with her in 2019 for the track Boy With Luv, from the album, MAP OF THE SOUL: PERSONA. However, since there hasn't been much exchange between the artists career-wise after the release of SUGA's Interlude in 2020, fans assumed that their interactions died down in the last few years. This was proven wrong by SUGA with the release of his documentary, SUGA: Road to D-Day, where the two were seen rekindling their friendship.pri⁷🐻💌@finiteinsevensuga and halsey performing suga's interlude and look at the smile he gave7720suga and halsey performing suga's interlude and look at the smile he gave https://t.co/AUlPBKFcsWclarisse 😼 d-day@hiHOBIhiMENT WITH HALSEY!802430MENT WITH HALSEY! https://t.co/jvRKCKQG7Wshu(ga)🥢@myglightthis makes me so happy i can’t even explain… the fact that halsey connected with yoongi so much when she listened to his mixtape and she immediately wanted to collab with him after..535117this makes me so happy i can’t even explain… the fact that halsey connected with yoongi so much when she listened to his mixtape and she immediately wanted to collab with him after.. https://t.co/6VOOeL1mA4lana⁷ on tour with txt ♡@jhslovesongif halsey is a special guest at yoongis show tonight and they perform suga’s interlude live together for the first time i will be jumping into oncoming traffic like that quite literally will be my last straw because if anyone deserves to be there to witness that ITS ME.1664297if halsey is a special guest at yoongis show tonight and they perform suga’s interlude live together for the first time i will be jumping into oncoming traffic like that quite literally will be my last straw because if anyone deserves to be there to witness that ITS ME.silvia 🥢@minygxpdif I ever go to a concert in US, im going to the LA shows because wdym they got burn it w/MAX and now SUGA’s interlude w/Halsey 756127if I ever go to a concert in US, im going to the LA shows because wdym they got burn it w/MAX and now SUGA’s interlude w/Halsey 😭슙 🥢@syoogasYOONGI AND HALSEY MAN I GOT CHILLS37695YOONGI AND HALSEY MAN I GOT CHILLS https://t.co/x1UnRwB3pqdaily yoonie@yooniestudioyoongi said “thank you halsey” and then they gave each other the biggest hug, I’M SOBBING 🫂21672yoongi said “thank you halsey” and then they gave each other the biggest hug, I’M SOBBING 😭🫂 https://t.co/7EmqZRTd36However, this wasn't the first time that Halsey supported BTS' SUGA. During the third day of BTS' Permission to Dance concert in L.A. back in 2021, the singer was among the audience, and was shown on the big screen as she proudly waved her ARMY BOMB when the BTS members greeted her with cheers. While this is the last LA concert date for the Agust D tour, fans still hold hope that there are more surprise guests in other venues, especially the other two dates that SUGA has in the U.S. at the Oakland Arena.
